I too am at day 22 with nothing as of when I went to work this morning. Hopefully something there when I get home. Well actually this is not my hatch but hatching for someone else.. ok more stress. lol I even double checked to make sure I counted the days right. I candled last night and could see movement in some and too dark to tell in others so still hoping.
My last 2 egg's I had in didnt hatch until day 23.I think the grandbaby messed with the bator a tad so they were a bit late hatching.The last one got stuckup a bit and had a foot sticking out all day.I finaly helped it out some.Hope they hatch for ya Update us on them.
I feel for you. I had a clutch under a broody hen that I let go until 25 days. Nothing happened. I had candled and seen movement, etc. Things just didn't work out. I had to take the eggs away and throw them out. My hen was devastated. I ended up having to dunk her in ice water to cure her of broodiness. Since then, I have another hen that went broody so she's now sitting on eggs. I've got my fingers crossed! Good luck.
